What’s on TV Sunday: ‘Sharknado: The 4th Awakens’ and ‘Summer With Monika’

Just when you thought it was safe, those shark-infested twisters are back — this time the kind that form on dry land — in “Sharknado: The 4th Awakens.” Meanwhile, Ingmar Bergman’s “Summer With Monika,” considered indecent in 1953, still ignites the screen. And Shout! Factory TV celebrates “Ultraman” on its 50th anniversary.

What’s on TV

SHARKNADO: THE 4TH AWAKENS (2016) 8 p.m. on Syfy. It has been five years since the last sharknado assaulted the planet, thanks to a tech wizard (Tommy Davidson) who figured out how to use nuclear reactors to short-circuit the man-devouring twisters. But his system doesn’t work on dry land — like Las Vegas, home to his shark-themed resort. Good thing our hero, Fin Shepard (Ian Ziering), is vacationing there after moving to Kansas. “‘The 4th Awakens’ is all over the place, both geographically and in its confused and unfocused storytelling,” Neil Genzlinger wrote in The New York Times. “Does the world need another ‘Sharknado’ movie after this one?”

FOX NEWS SUNDAY10 a.m. on Fox. Hillary Clinton gives what is being billed as her first televised interview since accepting the Democratic presidential nomination.

THE CIRCUS: INSIDE THE GREATEST POLITICAL SHOW ON EARTH8 p.m. on Showtime. The season ends with a recap of the Democratic National Convention.

CLOUDS OF SILS MARIA (2015) 10 p.m. on TMC; also on Amazon and iTunes. An Oscar nomination eluded her. But Kristen Stewart racked up the French equivalent of an Academy Award for her portrayal of a personal assistant who unwittingly mimics the role for which her boss — an aging French movie star played by Juliette Binoche — achieved stardom: an ingénue catastrophically involved with a lovesick older woman.

What’s Streaming

SUMMER WITH MONIKA (1953) on Amazon and iTunes. Monika (Harriet Andersson) and Harry (Lars Ekborg) — Stockholm teenagers with tense home lives — escape in a motorboat to an archipelago off the Baltic coast, where they while away the summer, making love in the open air. “‘Monika’ shows a director in absolute control of his medium and its singular expressivity,” Manohla Dargis wrote in 2007 in The Times about this boldly erotic 12th feature by Ingmar Bergman, which was considered indecent when it was first released in the United States.

ULTRAMAN: 50TH-ANNIVERSARY MARATHON3 p.m. on Shout! Factory TV.August Ragone, a Japanese pop-culture expert, hosts 12 episodes starring the Science Patrol and its monster-battling Ultra Crusader. In Japanese with English subtitles.
